The vast majority is the I/O subsystem (software or hardware), small percentage is bad memory or other server issue, and small percentage is SQL Server software bugs.

Corruption can't be prevented, but you can prepare for it and work around it - through backups and redundant copies of the database.

Hey Jeff - nothing explicit, but that's going to be the topic of my next article for SSC that I'll be writing this month.


Outstanding, Paul! I very much look forward to that. Thanks for the heads up!

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

With you Jeff - quite often I've seen articles on "how to find" and not as many on "what next"

Smart way to ask a question

There are naive questions, tedious questions, ill-phrased questions, questions put after inadequate self-criticism. But every question is a cry to understand (the world). There is no such thing as a dumb question. ― Carl Sagan
